Injury update: Earl Bennett officially has a concussion. He was back on the practice field Wednesday for the first time since Saturday, but did not participate and won’t play on Friday night in Carolina. Julius Peppers remained excused from practice. Corey Wootton left practice with tightness in his calf and Chris Conte had tightness in his hamstring. Tackle Jonathan Scott is still out with a knee injury. Henry Melton left practice as well after knocking knees, but it was nothing serious.

More Britton: Jermon Bushrod has returned to full team drills, but still may not play at all on Friday night, giving more opportunities to Eben Britton to impress. In addition to likely being the backup left tackle, keep an eye on Britton getting some time on the right side, as the staff is clearly pleased with his work thus far. “At this point I can say he’s definitely involved in being part of this roster – on a week-to-week basis, on a week-to-week basis. The 46,” said Trestman, referring to the 46 dressed players on game days.

Mixing up the ‘D’: We saw a new look on Tuesday when Melton rushed from a standing position. Shea McClellin did that as well in a blitz package, stacked with linebackers Lance Briggs and James Anderson, another example of Mel Tucker throwing some wrinkles into the defense.

Quick hits: The biggest pass play of the day came on a bullet from Josh McCown to Fendi Onobun. … Both Eric Weems and Joe Anderson took reps with the first-team receivers in Bennett’s absence. ... James Brown continues to take the majority of reps at right guard. There’s a long way to go until Week One, and first-rounder Kyle Long is still expected to be the starter, but he is far from winning the job outright.
